The Mastervolt AC Master power inverter produces a pure sine wave AC (Alternating Current) output from a DC (Direct Current) input from your boats battery bank. Because of the pure sine wave output, it is safe and reliable and prevents damage to the equipment it is connected to. The inverter is easy to install and features built in protection against over-temperature, overload, short circuit, high or low battery voltage and reverse polarity. The power inverter is robustly built and delivers the full output even in demanding conditions. The high frequency technology used eliminates noise typically associated with power inverters, such as buzzing or humming. It also features an automatic power saving mode, meaning a longer run time and less strain on your batteries. The 28220700 model is MasterBus compatible and can be used with remote control M70405080 for easy operation.

soft, cozy, lightweight. Drapes nicely or folds flat & even. Warm as liner to another blanket
Color: Orange, Size: Twin(60"x80"), Color: Orange, Size: Twin(60"x80")
Summer weight, soft feel, cozy. If using in cooler temps, then consider using it as a liner, then toss another blanket on top. Nice cozy way to trap in heat.
I love orange and was looking for a functional throw blanket. I didnt want the typical lap blanket size (50"x60"). I am tall and wanted something I can tuck my feet under and pull up to my chest when on the couch. But I also wanted it to be decorative when not in use. Not wanting a thick blanket for this purpose, I looked for a thin one of this style. It folds small and flat, OR drapes nicely when tossed. Even at twin size (60"x 80"), it still works as a "throw" blanket. It measures a little wider and aittle shorter so not perfect twin length.
It is thin, but not see through. Very soft. Haven't washed it yet, so hopefully it holds up.
ALSO, we have cats and dogs, so I am always looking at something to see if it can also be used for them. Depending on size, these blankets would make good furniture covers. Nicer than sheets, cheaper than pet products, thin enough to toss in washer, and a material that will stay in place on fabric furniture. Or just a blankey for pets that like to get cozy.
WHICH, at the time of my writing this, my recent rescue dog from the south is experiencing the cool fall temps of fall. She is snuggled up tight against me. I have this blanket as the base on me and the couch, and then a thicker fleece blanket on top of me and her. I just took a pic and will include it.

Comfortable, durable and great for everyday use
Color: Brown, Size: Queen(90"x90")
This blanket is super cozy and soft, and it’s true to size. I got the brown color, and the quality is excellent. I’ve washed it multiple times, and it comes out looking like new every time.
It’s on the thinner side but still keeps you warm—perfect for lounging on the couch or sitting by the fire. The fabric stretches a bit, but not in a way that would cause it to rip or break.
Pros:
Soft and cozy
True to size
Maintains quality after washing
Lightweight yet warm
Slight stretch without damage
Cons:
Thin, may not be sufficient for very cold nights
Conclusion:
Overall, this blanket is comfortable, durable, and great for everyday use. It’s ideal for relaxing at home while staying warm.

Nice Lightweight Blanket
Color: Light Camel, Size: King(108"x90")
I bought this because my winter blanket is too heavy for the summer. I'm a hot sleeper and have to have the temperature at 68 at night because the bedroom is upstairs above a garage and it gets warm. This blanket is very soft and not thick and I don't get hot. I have a queen size bed but I bought a king size so it looks more like a bedspread. It doesn't hang down far on one side but that is the side that people don't see so that's fine. If you like a blanket on the thinner side yet still warm enough, you will like this.
